I'm 17 and I know what you are going through. Presentations are very hard for me as well. I do have some tips that I find useful, and I hope you do as well: - Be calm. This is easier said than done, but seriously, being calm is the most important. Without feeling calm, you'll end up stressing yourself too much and therefore, stutter even more. - Talk slow and take breaks whenever you feel like it. If you feel like you are going to stutter, stop, pause, take a breath and say it even slower.. - Try to look at someone you feel comfortable with. This will hopefully keep you calm. - Use body language. Talk as if you mean it. Use your voice and make people know that you know what you are talking about. - Lastly, I want you to remember this because seriously, this is one thing that most stutterers don't know: PEOPLE DON'T CARE. I mean it. The people sittingt there and listening to your presentation are probably stresses themselves. Remember: YOU ARE AWESOME! YOU GOT THIS!
